The verdict
Ross holds 6 US patents across 4 technology areas, rank #42,715 of 50,000 tracked assignees.
Ross Operating Valve Company has been granted 6 US utility patents between 2016 and 2023, placing Ross Operating Valve Company at rank #42,715 across all assignees tracked by PlainPatent. This portfolio spans 4 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.2 claims per patent with primary concentration in F15B (SYSTEMS ACTING BY MEANS OF FLUIDS IN GENERAL; FLUID-PRESSURE ACTUATORS, e.g. SERVOMOTORS; DETAILS OF FLUID-PRESSURE SYSTEMS, NOT OTHERWISE PROVIDED FOR). As a US Corporation, Ross Operating Valve Company is one of the more focused assignees in the PatentsView dataset. By volume, Ross sits between Roly Llc (6 patents, rank #42,711) and Rules Based Medicine Inc. (6 patents, rank #42,719) - the closest US assignees by grant volume. The composite Innovation Score of 29.6/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 1 grants, compared with 5 in the 2015–2019 window, a -80% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. Ross Operating Valve Company's 15.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 4 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Ross Operating Valve Company against peers pursuing similar technology classes.

How to use this portfolio
Ross's 6 grants land it in the top 69% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
